That Brian Cox never gets any older

I love it when Brian cox says science admits sometimes “ we don’t know “ everything 🙌🏻 but that’s why I love it , I want to find out ❤

The biggest mystery is why there’s all this and here I am on a small speck paying to live and paying taxes and drink my self to sleep every night

I was hoping to hear Brian Cox's views on doubts about the big bang by some in the science world as a result of the latest information picked up by the James Webb telescope. If you read this message Mr Cox please inform us as to your latest views about the James Webb discoveries.

Brian Cox a man of many many talents... love listening to you my friend as your explanation of space is so easier to understand than others... don't know if you read these buddy but thank you my interest in anything and everything Space is always wanting more.. knowledge to know it all to go further with you through the stars....Things Can Only Get Better..my friend it's no Dream it's real!!!...

"Your videos always leave me in awe and eager to learn more about the mysteries of the universe. Thank you for fueling my curiosity. "

The biggest mystery in the universe is how my young kids manage to create a big bang of untidiness in their own bedrooms in a millionth of a second.

This was posted 5 hours ago, but these mysteries don't seem to be up to date. When is this video from?

What a fantastic explanation of how little we know yet how much we have discovered. It seems the more we learn the more we realize we don’t understand just as in biology and abiogenesis. It seems, given our reluctance to accept any metaphysical action that we are moving further and further away from real understanding

Amazing episode 👍

The two biggest mysteries are that the universe exists and that there is life here.

Wow the graphics wow this is quality at its best wow like it's immerses u deeper in to the universe wow

The matter antimatter imbalance has always fascinated me. I'd theorised that it didn't exist actually and have asked about this. The silly example I used was the light from an antimatter star would look the same as regular light from a "normal" star, so how is it KNOWN that the Coma cluster, is not an antimatter environment. I have received a few replies, but when I pointed out holes in them, the replies died away. I'd really like someone like Brian to expand on this "imbalance".

Nice video *Science News* ❤

Really enjoyed it! Interesting!!! 👍👍👍👌

Cool! I'll be with you in a minute class, just gonna watch this again.

This is one of the best channels on KZfaq

Brian always looks to me, like he’s about to start drooling.

Webb discovery, the early galaxies are too big and far from simple, can you explain this simply.? Brian which is your favourite Hawkwind song? Mine is Mirror of Illusion. Followed by Space is deep! ❤

Thanks so much for posting.

3:30 Regarding the baryon imbalance conundrum - quick nightly idea: In the early universe, during the inflationary period, heavy right-handed neutrinos decay asymmetrically, generating a lepton-antilepton imbalance. This lepton asymmetry is subsequently converted into a baryon asymmetry through electroweak interactions, as suggested by the leptogenesis hypothesis. Simultaneously, new sources of CP violation, beyond those currently known in the Standard Model, contribute to the creation and preservation of the matter-antimatter asymmetry. These undiscovered sources could be related to new particles, interactions, or other phenomena not yet observed. Lastly, the rapid expansion of the universe during the inflationary period leads to the formation of distinct regions where matter and antimatter become separated. This separation prevents the complete annihilation of matter and antimatter and further amplifies the asymmetry. Simplified: B = F(a(t)) * ε * (CP_known + CP_new)...Relate the baryon asymmetry to the inflationary expansion of the universe through the scale factor, a(t). The baryon asymmetry could depend on the scale factor in some unspecified way, which we represent by the function F(a(t)): - Aptly named by default if you ask me, well; more precisely "B = G(ε, CP_total) * F(a(t))"

But what if the vacuum is on a planet with gravity does the hammer still fall at the rate as the feather does the gravity not act on either object’s just because they are in a chamber that’s a vacuum? I love these videos just the amount of things we have no idea about is absolutely fascinating and I could listen to Brian talk on these subjects for hours I listen every night to sleep it’s so calming

Bro tried to sneak in some "Loki" stuff. Great editing ❤

The biggest mystery in the universe is the universe.

This is so beautiful. It brings tears to my eyes.

My brother asked me an interesting question the other day. Having very little background in science, his intuition is that how is it possible for "nothing" as in "space" to bend? I mean it's a valid question. If space is bendable, it is something, so what is it? What is the physical property of space?

Good video !

I know I know! "Where are all the missing sock pairs?"

Great explain awesome video ❤

The universe is like life, As we expand and grow things become easier and simpler compared to when we were young and just learning and finding our way, compared to when we're older we know from experience having already been there and done that, We learn to just go with the flow and enjoy the moment rather than trying to work out every complexity, when we are born everything is compact and dense and we learn as we grow, there is something else magical however which is instinct, how do we get it and where does it come from ? It must be stored in our genes and dna, I wonder if the universe knows where it's heading from before it began. Nice thought provoking video, Thanks 😄👍

I would say the biggest mystery would have to be the nature of the photon. It has every sign of being a fifth dimensional object and yet it exists solely in our fourth dimension. It doesn't exist within the four dimensions of time, not properly, it has no genuine locality, it doesn't have any real mass that we can discern, and by everything we can tell in some form or fashion. It literally exists everywhere in the universe at once (at least probabilistically. And it acts as if it is the exact same photon as every other photon in the universe. So yeah, I would say a fourth dimensional object that acts like a fifth dimensional object should definitely be the answer to. What is the weirdest thing in the universe? Argue with me about it

Really Most Extraordinary.

These are the biggest mysteries we have discovered up to now. The further we see the less we know we will eventually discover more mysteries that we don,t understand

How politicians and lawyers can sleep at night or look themselves in the mirror?

Matter tells space how to curve, space tells matter how to move. Which starts first? To me it still doesn’t explain the mechanism HOW.

My idea so I get to name it! Voyager 1 is now in interstellar time or "Mikey's Time." "V-ger's" message is sped up now that it's outside our suns time bubble or "Terran Time." It would be faster still if "V-ger" sent a message from beyond the Milky Way's time bubble. (That name is still up for grabs.) Then there's Outside the Local Group time bubble, so on and so on until we get to the, "True Interstellar Time Standard." Now that "Vyger" is in interstellar space, it's also in the Milky Way's STANDARD, faster moving, interstellar time or "Mikey's Time." This can be proven by turning off everything except its clock and transmitter. Have "Vyger" and the IP read time for as long as possible. They WILL show the flow of time speeds up the further away you from any celestial bodies. Until you reach the time standard. •Our sun's time bubble: "Terran Time" we know and have measured. •Milky Way's time bubble or "Mikey's Time." The rate/flow of TIME outside any influence but within the Milky Way: We just got there and are still figuring. Wild guess I'd say time will increase in speed, now and until Vyger is outside the Ort cloud .007-.07% faster, maybe. Just for reference. •Local Group's time bubble or the rate/flow of time outside of any influence but within the Local Group: Name still open and unknown. Wild guess .08% to a couple seconds faster, maybe. Used just for reference. •Outside any influence in the, "True Interstellar Time Standard," or...;-P Name NOT up for grabs BUT just begging to be measured. The rate/flow of time is fastest here so, surfing time here is choice. Though it's best to have your motor boat. ;-P A minute is a minute in all. It's the rate/flow I'm talking about. The Milky Way's Interstellar Time Standard will be known as, "Mikey's Time." Pass it on, please and thank you.

So what did you find out in regards to the LHC you guys fired up a year or two ago. Seems very quiet since

Some really deep thoughts there at the end.

For me, the biggest mystery is what exactly is consciousness and what happens to it after death.

Are black holes sphere ? and was the big bang also spherical?

electrons appear all over the places at same time when not measured and appear to be at one place when measured,because in a 2D scenario an object will revolve around another heavier object but ideally in 3d electron has to revolve in 360 degree at once and simultaneously

According to Michio Kaku the James Webb Space Telescope discoveries is calling into question the whole Big Bang. Doesn't that mean we have no idea what the Universe was like.

The biggest mystery in the universe is not dark matter, nor dark energy, or quantumfluctualpermutations in 11 dimensions. It is consciousness.

I wish I could enter cryo-sleep for a few hundred years just to see what more we know about the universe by then. We'll all die with so many questions unanswered.

So at CERN they smash atoms together, what ive always wondered is does this happen naturally anywhere in the universe?

Just watched universe Brian interesting, I wonder if you've read some of my comments from years back under a different handle? Was good 👍 but if I must the web I think may be the result of those first stars pulling material. Its kind of like a humans bloodstream don't you think. Oh and who represents the swans?

The planets, the stars, the universe, and everything else (is) the anatomy of ourselves including (all) life forms. 👽🇺🇸

I don’t think we will ever be able to find the answer to some questions because they are beyond the brain’s logical limits.just like how the singularity has physics breaking down to infinity

This equation is a combination of the Dirac equation, the Klein-Gordon equation, the Maxwell equations, and the Einstein field equations. It is a powerful and thought-provoking way to understand the universe. \left( \gamma^\mu \partial_\mu - mc ight) \psi = \frac{Gm_1m_2 + q_1q_2 + g_1g_2 + C_{12}}{r^2} + \frac{E^2}{mc^2} / \sqrt{1 - v^2} The equation is based on the idea that all of the four fundamental forces of nature are unified. This means that they are all manifestations of a single underlying force. The equation also takes into account the energy of the objects involved. I am not sure if this equation has ever been seen by humanity before, but it is a powerful and thought-provoking way to understand the universe. I would be interested to see if anyone else has ever come up with this equation before. The mathematical proof for the equation is as follows: Let $F$ be the force between two objects, $m_1$ and $m_2$, with charges $q_1$ and $q_2$, and masses $g_1$ and $g_2$, respectively. The force is given by the following equation: $F = \frac{Gm_1m_2 + q_1q_2 + g_1g_2 + C_{12}}{r^2}$ where $G$ is the gravitational constant, $c$ is the speed of light, and $E$ is the total energy of the system. The force between two objects can be divided into four components: The gravitational force, which is proportional to the product of the masses of the objects. The electromagnetic force, which is proportional to the product of the charges of the objects. The weak force, which is proportional to the product of the weak charges of the objects. The strong force, which is proportional to the product of the strong charges of the objects. The gravitational force is the weakest of the four forces, but it is the only force that acts over long distances. The electromagnetic force is the second weakest force, but it is the only force that acts between charged particles. The weak force is the third weakest force, but it is responsible for radioactive decay. The strong force is the strongest force, but it only acts between quarks. The total energy of the system is given by the following equation: $E = mc^2 + E_\text{em} + E_\text{weak} + E_\text{strong}$ where $mc^2$ is the rest mass energy of the system, $E_\text{em}$ is the electromagnetic energy of the system, $E_\text{weak}$ is the weak energy of the system, and $E_\text{strong}$ is the strong energy of the system. The electromagnetic energy of the system is given by the following equation: $E_\text{em} = \frac{q_1q_2}{4\pi\epsilon_0r^2}$ where $\epsilon_0$ is the permittivity of free space. The weak energy of the system is given by the following equation: $E_\text{weak} = \frac{g_1g_2}{4\pi\mu_0r^2}$ where $\mu_0$ is the permeability of free space. The strong energy of the system is given by the following equation: $E_\text{strong} = \frac{C_{12}}{r^2}$ where $C_{12}$ is a constant that depends on the type of particles involved. Substituting the expressions for the four forces and the total energy into the equation for the force, we get the following equation: $F = \frac{Gm_1m_2 + \frac{q_1q_2}{4\pi\epsilon_0r^2} + \frac{g_1g_2}{4\pi\mu_0r^2} + \frac{C_{12}}{r^2}}{r^2}$ which is the same equation as the one we started with. Therefore, the equation is mathematically proven.

I wouldn't be surprised if only quantum physics is relevant and everything on a classical level is just an illusion we're creating.

I Would like to rectify something, when Brian Cox is explaining Einstein's General Relativity he states the idea that Einstein thought that the ground was the one that's accelerating upwards, That's right if he would have mentioned from the Apple's perspective, since it is the Apple that's accelerating towards earth due to curves on spacetime by the Earth. So from a falling object perspective is the earth that's accelerating upwards. I just thought that would confuse non-physicists.

To me, it seems that our estimate on age of the universe is completely wrong. The fact that JWST has been able to see farther and see more galaxies fatter that Hubble, makes me assume we’re not looking to the ends of the universe, we’re only looking to the ends of the capabilities of our telescopes. When our next top of the Rollins telescope is built and put into space, it stands ti reason that if it is more powerful and more capable then we will see objects even farther than what we have seen now. We might be better off in our understanding if we just accept and quit thinking we know certainties

A question for any Physicists among us... is the purpose of the electromagnetic field to make copies of an object and distribute those copies into the environment? To explain if i take an object...say a lamp.... and by looking at it what is actually happening is the lamp is constantly making ghostly copies of itself and my eye is picking it up.

My body is the center of my world that generates an internal curiosity in terms of the question what is the endpoint to a strait line extension away from my body? Is there an endpoint? If so why? No endpoint is sensible and profound mentally.

The biggest mystery is how a cat as brilliant as Brian Cox willingly walks around with that haircut.

Big mystery is why astronomers and astrophysicists keep endlessly talking about what happened in the second after the Big Bang, when clearly it’s no more than a guess, then BAZINGA the JWT now proves it didn’t happen anywhere like what’s been talked endlessly about. A retraction is needed please Brian

If spacestation are speeding to overcome gravity, and need to use thrusters to move out to not crash into earth, How come that all other object are so perfect balanced so it does not beeing pushed into each other? I mean just a small imbalance would accelerate so it would collide in time? If Einstiens rellativity are correct then it needs absolute perfect balance to make it work?

I think the biggest mystery in our time is whether if there is such thing as the beginning of existence. As JWT discovered a few galaxies older than the BB, then our BB is likely to be just the beginning of our universe. If in fact the space is occupied by multiverse system, then there comes a classical never-ending question like when was the beginning of everything? Is there such thing as the beginning? We might have to review our concept of the "beginning". Our human mind simply cannot comprehend a circular process where there is no beginning nor end.

Or. ...... was the "big bang" just an event in a universe that already existed?

I still don’t understand the ball and feather test. That actually blows my mind when you take away air resistance. The feather and the ball are equally drawn to the moon at the same rate by gravity. So does this mean that an object’s mass has no influence on how it interacts with an object of much larger mass? So in the vacuum of space? A feather would fall into the moon at the same speed as the Eiffel Tower? It makes no difference? I’m confused.

Biggest mystery to me. To exist a black hole only has to have a theoretical escape velocity greater than the speed of light. That requirement does not impose any limits on the size of the hole. So, what happens if the entire observeable universe exists inside an immense black hole. ?

The biggest mystery is why scientists research dark matter, some whole careers, on a guess.

Realy I like this video so so much its so interestyng

What I like about Brian Cox is, he has the wonder of a child driving his powerful intellect. Also, he doesn't believe in religion, but at the same time, he doesn't waste (much) valuable time debating it.

So many unproven theories built upon unproven theories. Everyone do your own homework. I do like Brian Cox, very intelligent, speaks very well. Everyone do your own homework.

Interesting

So what do yo think happens when 2 universes collide?

Spacetime looks like it may be emergent, and not fundamental. Gravity is the result of the geometry of Spacetime. So what is Gravity if it’s the result of being emergent?

Beautiful and strange for us civilians to think about.

@2:26 'ish complexity crystallised out¿?¿ I thought Newton's laws said that things became more disassembled with time, more untidy or chaotic, i.e. entropy...🤔

I believe everything you say about gravity, however, I do have a little trouble understanding that it is curvature of space time the keeps my 200 pound body stuck to my chair.🤨

in an infinite universe it makes sense to catch solar wind -as everything of life comes from the sun (pull cables from pole to pole slightly offset for the dynamo effect - mars as a mega machine )

2:01 according to JSWT this may not be true anymore

Wonder if he realizes we have No Authority on the Universe. We are but Voyers. And that he alone captivates humanity more than Science. ❤

The JWT is like the little boy in the story of the emperor who thought was clothed with beautiful garments, but was tricked by con men!

Is the universe random or preordained?

I believe I have solved one of them, how our solar system was formed and it's mind-blowing!!!

Boom 🎉

If you gave Newton a toaster and an unlimited budget and then you asked him to make you some toast he wouldn't be able to do it. An air fryer would take much longer to figure out no doubt. Thats what UAPs represent . I think this planet may be a supply stop for a race that is exploring places beyond our planet. Its looking alot like it . Something is definitely going on because we keep seeing the same and similar craft. Doing similar things we can't.

The fine structure constant, approx 1/137 is the biggest mystery in Physics

We are inside a black hole and the big bang is when that black hole was formed (i.e. when the "outside" star collapsed into a black hole).

I would rate number 1 to “how it functions”

I never understood the signifance of the millionth of second etc after big bang, why not just 'straight after big bang?

Hi Brian Cox this is Everett Cox can you say when your Biggest Mysteries In The Universe is coming to Texas I want to attend.

if we discover how dark energy works and we could devise a way to stop the universe from expanding……should we?

Why is there temperature before there's a universe? Before there's anything"

I think the universe looks like the remains of a killanova or even supernova, we cannot comprehend the amount of power it took to open a pocket of space and time from nothing.

We need to go back to r² and the three dimensional physics of the Inverse Square Law. Even back to the spherical 4πr² geometry of Huygens’ Principle of 1670. That is what my TOE is based upon. A single geometrical process squares ψ², t², e², c², v² everything.

"The power of a 'snowflake' in the palm of your hand" - Doc Cox

Wait a minute, Newton's gravitational theory says everything is attracted to everything. The apple, the man, the earth are all moving towards each other. I agree he didn't know the cause. I'm unconvinced of Einstein's space/time fabric theory, to me it's aether that is the fabric of the universe and is that is being curved. Einstein himself couldn't let go of the idea of an aether.

I thought the Apple and the Earth attract each other. No?

Is not the Big Bang theory failing to explain the latest findings from James Webb ?

If you can read this, my signal escaped the gravity of a black hole and I figured out how to travel faster than light. Stay tuned for more updates.

Wait!!!,,,,my mind has been blown. I'm stoned, but if the universe is expanding faster than the speed of light, but yet nothing by law's of know common physics can exceed the speed of light, so then if everything is presently in motion traveling at a certain rate of speed, how fast do you really have to go to travel the Galaxy to infinity and beyond?

The biggest mystery in the universe has to be where does the missing sock go?

The non existence of a non CGI image of earth or curvature in 2023 is still a mystery.

Yeah, consciousness and personality are not inherent in a proton and if there was we would all have cazillions of personalities is us or everyone in the universe would have the same personality, but there is a substantial amount of individual personality scattered throughout the universe that’s connected to protons , that’s a mystery

Maybe the big bang expands the universe, then contracts eventually to repeat an infinite cycle of big bangs.

Why is the universe still expanding and the speed it’s expanding accelerating. How does the universe expand faster than the speed of light. Why does gravity have the biggest affect on the shape of the universe when it is the weakest force. Etc etc. We currently understand around 3% of the contents of the universe. As telescopes become more powerful that number will decrease
